Eclipse意外停机后，Eclipse无法正常工作。这是与我尝试运行Eclipse时写入的日志文件相对应的错误。

Answer 1

如果有效，请尝试更改工作区。要强制更改工作区提示，请进行以下更改。

<Eclipse_root_dir>\configuration\.settings\org.eclipse.ui.ide.prefs and set SHOW_WORKSPACE_SELECTION_DIALOG to true

如果可行，请转到workspace \ .metadata \ .plugins \ org.eclipse.core.resources并删除.snap文件。
如果＃2不起作用，请尝试删除workspace \ .metadata \ .plugins \ org.eclipse.core.resources文件夹。 请确保备份，以防将来需要。

Answer 2

经过大约30-45分钟的试验后，我发现％eclipse_workspace％.metadata.plugins \ org.eclipse.core.resources.root中有一个文件，扩展名为＃34; .tree＆＃34;。我删除了它，我可以重新启动eclipse。虽然我的工作区中的所有项目都已删除

Answer 3

我面临同样的问题并尝试了很多，但以下其中一项工作在我的案例中：

只是导航到 WorkSpace.metadata.plugins \ org.eclipse.core.resources.root
删除* .tree文件

希望它适用于你的情况 - 祝你好运。

Answer 4

当我遇到与原始帖子中提到的相同的问题时，删除.snap文件对我有用。 workspace.metadata.plugins \ org.eclipse.core.resources并删除.snap文件。

谢谢！

Answer 5

我遇到了同样的问题，user1401472s答案的选项1对我有用从损坏的工作区中还原项目就像通过以下方式将它们从旧工作区重新导入到新工作区中一样简单：文件->导入->常规->“现有工作区中的项目”，然后选择旧工作区文件夹作为根目录-目录。

编辑：这是在Windows 10上
